Part of photography's history

Lenses for the SQ series are coming in two variants - the older "S" type and the newer "PS" type. The PS types were introduced starting 1986 and, like their PE sisters, redesigned - both optically and mechanically.

On top of the redesign they introduced half-stop iris clicks, better mechanics, addressed light leakages in some lenses and tackled the vignetting of the old S 50 by increasing the filter size.
